mikuscore mikuscore is a browser-based local score editor focused on preserving existing MusicXML structure while editing. It supports loading MusicXML/ABC, score preview, note editing, playback, and export/download as MusicXML/ABC/MIDI in one screen. mikuscore intentionally keeps the feature set small to make score editing practical and fast, especially on smartphones. It is smartphone-centered, but it can also be used on PCs. Workflow: 1) Choose input and load 2) Select from score preview 3) Edit notes 4) Verify by playback and export/download. After loading, click notes in the score to select targets, then adjust pitch and duration. Use tools like MuseScore for large-scale or complex work, and use mikuscore for quick input or focused partial tasks. GitHub
1Input To use mikuscore, first load your score here (from file/source) or create a new score. You can move to Score/Edit/Export after completing this step.
2Score This screen is for checking the loaded score, trying quick playback, and selecting the measure to edit. Select a note in the target measure here, then go to Edit to apply actual note changes in that selected measure.
Playback: idle
3Edit In Edit, start by converting a rest to a note, then adjust notes in the selected measure: split notes, change pitch, add accidentals, and change duration. You can also try quick playback. Press Apply to reflect your edits back to Score, or Discard to cancel current measure edits. Use the arrow buttons to move between measures. Editing is intentionally limited to avoid breaking MusicXML structure, so use a dedicated notation app for fine-grained editing. Track: -
No measure selected
Click a measure in the score to select it
4Export Export is where you take your work out of mikuscore. The main flow is exporting your edited result as MusicXML. In addition, mikuscore also supports ABC export and lightweight MIDI output for quick checks. MIDI export is handy for simple confirmation, while complex production/export work is best done in dedicated software.
